I suppose one of the issues is that traditionally they type of person that bought such a vehicle would forgive some foibles as it came with the territory and it was overall capability they were after.
They were generally pragmatic and practical types, they would accept it being more 'agricultural' and if there was a minor issue, they either fixed it, ignored it or replaced it with something better. A mate of mine had a County and more than a few times we sent him home with a pair of dolphin torchs strapped to the bonnet or a 12V starter pack on the passenger seat (replacing the vehicle batteries), but it always got him home.
Now they are trying to sell the same quality mechanical product with the added complexity of electronics at a marked up price to a demographic that isn't after the agricultural version, they want the refined one that does everything, but for the $$ they are paying aren't going to accept that they may have to spend a day a month 'tinkering'.
Unfortunately the electronic based systems are conducive to someone tinkering with them and are operating in an environment that will reveal any faults pretty quickly (dusty and wet with vibrations and heat cycles) and a CANBUS system is beyond your home mechanic.
Any issue will be a tilt-tray back to the dealer and on social media and its a downward spiral of bad publicity from there.
I'm sure its not an impossible fix, but it would take stopping production, re-designing vehicle systems and starting again (and probably finding a whole new bunch of issues).
Personally, I think the green oval has managed to kill its reputation and coming back will be very difficult when there are now other options. The brand used to represent rugged reliability (yes, expectations were lower back in the day), exploration and adventure, now there is nothing in the range that represents that.
